First I just want to say that I think this newsgroup is outstanding. I have been reading many posts and have learned much from you folks. I'm just starting out in this hobby and am in the very beginning stages of building my layout. With that said I'm itching to start buying some rolling stock. I want to model my area, Central Massachusetts, Worcester, West Boylston, Millbury, etc. My question is what are some of the names might I find on engines in this area. I see CSX quite a bit but not much else.For instance, today I did see a CSX engine go by with a green HLCX engine behind it. I'm still too new to this to know where or what HLCX stands for. But I also know you folks will absolutely know.
